A photo purportedly showing a naked 15-year-old has made its way onto the iPhone App Store through an app called BeautyMeter this week, despite Apple’s strong stance against objectionable content in the store.

Last week the application “Hottest Apps” was quickly pulled from the App Store due to “objectionable content,” namely, female nudity. It was adult female nudity, though, unlike today’s whopping PR nightmare for the iPhone.

BeautyMeter allows users to upload photos of themselves and subsequently rate one another on body, face, and clothing appeal. If you’ve been to Hot or Not, you get the idea. Today, an iPhone app review site called KRAPPS found a picture of what appears to be a 15-year-old girl topless and partially nude below the waist in BeautyMeter. Nearly 5,000 users have voted on the picture.

As of this posting, the application is still available in the app store, though the picture may have been removed. I would expect the app to at least get pulled for review before day’s end.

According to the developer’s website, funnymals.com, they do not review submissions on a photo by photo basis. Rather, they go in and clean up “from time to time.” This certainly gives plenty of room for photos like the illegal nude in question to slip through. Users have even commented in the app store that, “There shouldnt be 14 year olds nude on there [sic].”

The developer does supposedly capture your iPhone’s unique device ID when you upload a photo, making it possible to track down anyone who has posted illegal content. Neither Apple nor Funnymal will likely have legal liability in this case, though it does raise questions as to how Apple will handle user-generated content in future applications.
